MACHINE FOR SHAPlN G BOOTS OR SHOES.

SPECIFICATEON forming part of Letters Patent No. 589,732, datedSeptember '7, 1897'.

Application filed December 12, 1895. Renewed March 22, 1897. Serial No.628,745. (No modeli To all whom may concern:

Be it known that I, JOHN E. Law'ron, o Swampscott, county of Essex,State of Massachusetts, have invented an Improvement in Machines forShaping Boots or Shoes, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representinglike parts.

This invention has for its object to improve the construction of shapingor treein g inachines especially adapted for shaping or treeingbutton-boots, it being so constructed and arranged that a button-bootmay be drawn onto the form while buttoned, and after it has been shapedor treated in any desirable way may be withdrawn from said form withoutunbuttouin g, thereby greatly facilitating the work and also givingshape to the ankle'and top portions and the invention consistsin detailsof construction, as will be hereinafter described. 7

Figure 1 shows in side elevation a shapingmachine embodying thisinvention; Fig. 2, a detail of the form, showing the fore part drawnout.

Thestandard or base A has at its upper end a socketed frame B, whichreceives the cylindrical hub of the cxpansible form. The main frame a ofthe expansible form has at its knee end this cylindrical hub, and saidframe a constitutes the front leg portion of the form. The back legportion 1) is supported by the frame a, it being hollowed out andprovided at one end with a heel b and at its opposite end with a holeadapted to receive a guidcpin U, projecting from the frame.

The back leg portion 1) is supported by a spring or springs (see Fig. 1)attached to the knee end of the frame and extending forward and engagingpins on the back leg part in adconnected loosely at one end to the rod 0and at its opposite end to the back leg portion. The back leg portion isacted upon at two points some distance from each other and is bodilymoved, being guided in such movement by the guide-pin 11 The rod 0projects axially through the cylindrical hub and is acted upon by abell-crank lever d, pivoted at (Z to a stand or post, one arm of saidlever being connected by a rod with a treadle d pivoted at (Z As thetreadle is depressed the rod 0 is moved longitudinally, thereby movingthe back leg portion outward.

The frame-bar or front leg portion a of the form is herein representedas having a T- shaped rib a, which receives upon it a slide a having agroove shaped to receive said rib and slide along thereon freely. Thisslide a is herein represented as formed to constitute a shin-piece ofthe expansible form, and it has a spring-pressed pin a which bears uponthe rib c4, and when the shin-piece is withdrawn to its fullest extentit enters a notch a formed therein.

The shin-piece a? is formed at its outer end with a flat face, againstwhich abuts the upper fiat face of the detachable fore part 6. One ofthe abutting faces has a dovetailed groove and the other a projectionshaped to enter it, and a spriugpressed pin e passes through or isarranged on the fore part, which by entering the socket in the frontface of the shinpiece assists in securing the parts together.

The shank portion of the fore part c is cut away or removed adjacent theheel, the line of severance being more or less oblique, and the materialso removed is sufficient to so materially diminish the thickness of thefore part at the instep as to bring the measurement at such point thesame or less than the ankle or ball measurement. By thus reducing themeasurement at this point it will be seen that when the fore part isdrawn out, as shown in Fig. 2, the heel measurement of the form will bereduced to or less than the ankle measurement, and, in fact, themeasurements of the form are for the most part materially less than theankle measurement, and as a result a buttoned boot can be drawn onto theform easily. fore part is returned to its proper place, represented inFig. l, and the form may then be expanded and the buttoned boot 'or shoeshaped. The buttoned boot 01'. shoe thus shaped can then be withdrawnfrom the form without unbuttoning and its shape thereby leftundisturbed. To assist in this work, the slide carrying the fore part ismade to grad ually approach the heel as it is drawn out, this resultbeing accomplished by providing an inclined raceway or support fortheslide, but while this feature does materially assist in accomplishingtheessential object of this invention-namely, to draw onto and off of anexpansible forma buttoned boot or sh0e yet I do not desire to limit myinvention to an expansible form having a fore part and heel so arrangedthat one gradually approaches the other as the boot is withdrawn.

I claim- 1. In a shaping'machine for boots and shoes, the combination ofa back leg portion having a heel, a front leg portion having an obliqueface, a fore-part support sliding on said oblique face and a fore partdetachably con;

nected to said support,having its shank adjacentthe heel removed, andmeans for lim- After or as the boot is drawn on the said pin,substantially as described.

In a shaping-machine forboots and shoes. an expansible formcomprisingafront and a back leg portion, means for moving thelatterbodily with relation to the former, a guidepin for said back legportion, at the rear end thereof, and a spring supporting said back legportion which engages it in advance of said guide-pin, substantially asdescribed.

t. In a shaping-machine forboots and shoes, a form having a frame, ashin-piece sliding thereon and carryinga fore part,and a springpinadapted to limit the withdrawal of said shin-piece, and when operated topermit detachment of said shin-piece, substantially as described.

5. In ashapinganachiue for boots and shoes. an expansible formcomprising a back leg portion having a heel, a front leg portion havingan oblique face, an expanding device for moving said back leg portionaway from said front leg portion, to expand the form, a forepart supportsliding on said oblique face, a

fore part detachably connected to said support-,the instep and heelmeasurements of the form both being reducible to the ankle measurement,when said fore part is drawn out and means for limiting withdrawal orsaid fore-part support, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribingWitnesses.

JOHN E. LAVVTON.
